My club is starting up an event for antique military rifles. After
hearing all of the rave reviews here and other places, I went out and
bought a Mosin Nagant 91/30 the other day. It seems to be in fairly
good condition and shoots reliably but is consistently about 8 or 9
inches high at 50 yards which is the distance for our event. The rear
sight is down all the way. The gun must be totally stock for the most
part - no scopes or replacement sights are allowed which sevely limits
the options.

One thing I was thinking about was cutting the notch in the rear sight
a little deeper. Any ideas on that or anything else?
